Badly. The fan runs continually, and it's much louder than the Northwood (whose fan turns off time to time).

It is safe, as less well-ventilated laptops manage to get by with temps like that for years.

Some partial results, a few of which I'm not sure of. HP DV6000, AMD edition, TL60/nVidia6150, Vista. Default voltage: 20w idle, screen on dimmest, no wifi 25w idle, screen on brightest, no wifi 72w load (dual prime95), screen brightest Undervolted: 19w idle, screen on dimmest Light usage: Not sure,...

Thanks for all the replies. I'm still very confused. I guess I'm the only one. ...what does (1<< 8 ) even mean?! I understand the formula for voltage and frequency, but I can't see how it applies to the code in the file, or in what you've shown. Give me differential equations, and I can probably un...

The frequency and voltage are represented by id numbers, fid and vid: frequency = 800 + fid * 100 millivolts = 1550 - vid * 25 Well, back to this: for (j = 0; j < data->numps; j++) { powernow_table[j].index = pst[j].fid; /* lower 8 bits */ powernow_table[j].index |= (pst[j].vid << 8); /* upper 8 bit...

Don't forget Socket 754, in case you have old DDR lying around (and they have AGP boards). Their (preferably RevE4) 90nm cpus get good power consumption too.

But video playing doesn't really need a discrete video anyways.

so, there's no other way to do it? you have to recompile the kernel? I have no clue how to do that...I'm using the beta of the 7.10 ubuntu at the moment, but I haven't been using it for the sole reason that I cannot undervolt. The only other way (other than switching mobos) is recompiling the ACPI ...

I think there's a linux-phc patch for AMD too, hidden somewhere in the mentioned link. It's been there for a while, but they don't mention it on the front page (probably because of bugginess).

seconding the "it's the cpu" deal.

I'd scan my drive for bad sectors (ie hw prob that'll go away with the new rig). You are shutting down properly, right?

Driver conflict shouldn't cause this.

I would assume all new boards require it, there's not an easy way for them to know that it's ok to draw from the regular connector because of a low power cpu. BTW, the connectors quite literally burn (turn brown at least, but possibly worse) when they go over spec, which makes me wonder about those ...

Some boards were designed to fall back on the regular connector I guess. That was a while ago when they were still switching over to the new design. The regular connector can only supply significantly less than 120w to the cpu, so I'm pretty sure any motherboard that supports the hotter P4s would r...

If it's a firewall it's probably not gonna use the disk much, just spin it down.

The 71c idle temp does not seem normal at all, so I would think that there's something wrong, either reading wrong or the heatsink is not on right.

I'd think the flat metal side, if possible. The heat comes from inside the HD, not the electronics, so the electronics would sorta keep the air from going directly where it needs to be.

??? Then it's a 802.11 n AP, not a g . Because n supports 108Mbps, g 54. But if your laptop has g, I don't think it's worth getting an 108Mbps AP. Also see Wikipedia . N is more than 108. The 108mbps was a propriety extension by Atheros from before N came about, so you'd need a 108 Atheros card to ...

The period was throwing the link off

Nforce 2? That don't sound right...

What socket btw?

And you might want to resolve the stability issues before you undervolt.
When you do, use RMClock to do it.

Sounds like a Flash problem.

IE Flash+8.1+yahoo = crash

And your other versions apparently don't have Flash installed. So they can go on yahoo fine but can't play the cnn flash videos.


I'm guessing reinstalling flash might fix it.

Core temperature does not work on Brisbane cpus.

So those 20-something temps are from the core and are thus off. Ignore them.

I'm guessing the 62c would be the chipset, it gets pretty hot. Seems the only problem with Speedfan is figuring which temp is which.

The Athlon XP diode is not readable directly by software like in the newer chips. I think the motherboard maker has to wire it up to a sensor chip, thus it's rarely enabled.

Well there's 50-something watts of other components...

However, I just noticed that Powernow is usually not enabled on desktops. You can enable it, but only certain boards support the ever-important voltage changing.

In your case it's the cpu. Rev E6 cpus were limited to 1.1v.

Generally it can be both. Some motherboards don't support the bottommost voltages, I've seen some that 'only' go down to 0.9v.

Found a Barton chip lying around, tested it. Test consisted of booting into Linux, taking idle watts, running Prime95 and taking load watts, then rebooting into BIOS and taking the watts there. Figures below are straight from the wall. Obviously there was a lot of overhead from the setup. PowerNow w...

Definite maybe... too bad specs are nowhere to be seen. Can anybody mention a typical low-load efficiency % for a 300w psu?

So my desktop is sucking down 70w at idle... I really cannot figure out why, there seems to be 20-30w unaccounted for. Ideas? Config: Antec MT300 PSU, can't find specs but guessing 70% efficiency.
